## What it is
An open library of adversary emulation plans from MITRE's Center for Threat-Informed Defense, mapping real-world adversary TTPs to MITRE ATT&CK. It includes full emulation plans for specific threat actors and micro emulation plans for compound behaviors like webshells.

## Use cases
- test my defenses against real-world adversary TTPs
- run a red team exercise emulating APT29
- build purple team exercises based on MITRE ATT&CK
- emulate webshell behaviors to validate detections
- prioritize security controls based on actual threat actor behavior

## When to choose
- you want structured, ATT&CK-mapped emulation plans for red or purple teaming
- you need to validate detections against real-world adversary behavior
- you want free, vendor-neutral threat emulation content

## When to avoid
- you need an automated attack execution framework - this provides plans, not tooling
- you want vulnerability scanning or general penetration testing tooling
- you need adversary intelligence beyond the included summaries

## Facets
- artifact type: dataset
- maturity: active
- function: security, penetration-testing, developer-tools
- domain: security, penetration-testing
- platform: cross-platform
- tags: mitre-attack, red-team, adversary-emulation, threat-intelligence, cyber-threat-intelligence, purple-team
